Head of Tzomet Institute Clarifies 'Germalit' Elevator Device Is Only for Mobility-Impaired on Shabbat

Rabbi Menachem Perl, head of the Tzomet Institute, addressed recent controversy surrounding the 'Germalit' device, which enables mobility-impaired individuals to summon an elevator on Shabbat using a halachic indirect action mechanism. In an interview with Channel 7, Rabbi Perl explained that the device is a limited halachic solution intended solely for those with walking disabilities who have no alternative means to use a Shabbat elevator. He emphasized that the Germalit is not meant to replace Shabbat elevators where they are available.

Rabbi Perl detailed the device's operation: it uses a mechanical button completely disconnected from the elevator's electrical system. A separate electronic system periodically scans the button's status and only activates the elevator button after detecting a change, classifying the action as "grama" (indirect action) under Jewish law. This distinction allows its use in cases of significant need, such as for those who would otherwise be unable to leave their homes on Shabbat.

Responding to online criticism, Rabbi Perl noted much of it stems from misunderstanding both the device's function and the halachic principles behind it. He stressed that the device is not permitted for general use and cited an example where a luxury hotel in Eilat requested multiple units but was refused because hotels are obligated to operate Shabbat elevators.

Rabbi Perl acknowledged that some religious communities reject even Shabbat elevators and thus oppose the Germalit device. Nonetheless, the Tzomet Institute relies on rulings from prominent rabbis including Yehoshua Neuwirth, Shlomo Zalman Auerbach, and Ovadia Yosef, who support the use of grama devices in appropriate cases. Rabbi Perl concluded that the device significantly eases life for mobility-impaired individuals who otherwise cannot leave their homes on Shabbat, not only to attend synagogue but for basic mobility.
